Abstract
The Ne-19(p,gamma)Na-20 as well as the Ne-19(d,n)Na-20 reaction have b een studied in inverse kinematics using Ne-19 radioactive beams. Upper and lower limits for the Ne-19(p,gamma)Na-20 astrophysical reaction r ate have been deduced, for the first time on the basis of direct exper imental data. It is concluded that the transition from the hot-CNO cyc le to the rp-process in explosive hydrogen burning is most likely gove rned by the preceeding O-15(alpha,gamma)Ne-19 reaction.
